6 Claims.

This invention relates to apparatus for dispensing gasoline or otherliquids, and chiefly concerns the provision of locking means for lockingthe hose nozzle to a pump casing and simuljtaneous1y locking the controlapparatus for the In the locking of gasoline dispensers a number ofconditions are met with which may be overcome individually in a simplemanner by multiple locking operations; however, where carelessness ofemployees and question of economy of time is concerned it is importantto simplify such locking operations to their greatest extent. As is wellknown in this art, a telephone hook type of nozzle support is commonlyutilized to support the nozzle of the hose when the same is ininoperative position. This support in many cases either electrically ormechanically controls the dispenser, and the weight of the nozzle on Q;the hook actuates the same to render the pump inoperative. It will thusbe obvious that upon closing a gasoline station for the night, it isextremely important to lock this member against accidental or maliciousdisplacement. It is equally important to lock the nozzle in place, asthis member is usually provided with a gasoline release trigger whichcontrols the release valve therein. Any failure on the part of the firstnamed release valve or control would of course '30 permit gasoline toenterinto the hose, and if the trigger were free to be moved by any onewith a mischievous or malicious intent after the station has beenclosed, a fire hazard or at least a loss would be experienced by thestation.

' The hoze nozzle, in addition to this, is itself a valuable piece ofequipment and is easily unscrewed from the hose itself, and therefore issubject to theft. It is also deemed necessary to protect the outputopening of the nozzle against the entry of water in the form of eitherrain or snow when the same is not in active use. With the aboveenumerated conditions and requirements in view, this invention has forits object a locking means for locking the control member againstmanipulation, and simultaneously performing other distinct lockingoperations, such as looking a hose nozzle against theft, locking thetrigger of the hose nozzle against manipulation, and locking the freeend of the nozzle within the dispenser casing where it is protected fromthe elements.

These and other objects and advantages of the present invention are morespecifically described and set forth in the accompanying specificationand drawing.

In the drawing:

Fig. 1 is a front elevation of a gasoline dispenser diagrammaticallyshowing the main operating units and their association to the presentinvention.

Fig. 2 is an enlarged cross section through the dispenser casingadjacent the hose mounting.

Fig. 3 is a section on the line 33 of Fig. 2.

Fig. 4. is a perspective View of the bracket.

In the specification, the numeral 1 indicates a gasoline dispensercasing or housing, within which, as is shown diagrammatically in Fig. 1,is suitably mounted a fiuid pressure supply device consisting of a motordriven pump 2 which is adapted to pump liquid from the supply line 3 tothe feed line 4 and from thence through the meter mechanism 5 to theflexible hose 6 through a suitable fitting in the dispenser casing. Thefree end of the hose is provided with a nozzle 7 which is preferably ofthe type shown and having T5 a trigger 8 manually movable from theposition shown in Fig. 2, to a position adjacent the nozzle to open asuitable valve therein. The nozzle is also provided with a trigger guard9 which extends around the trigger and has an extending 8 flat portion10 in close proximity to the tip of the trigger. A flexible nozzle end11 is secured to the free end of the nozzle, while the hilt end of thenozzle is shouldered at 12, for purposes hereinafter set forth. Withinone wall of the casing a bracket 13 is secured in any suitable manner,and at its central portion is provided with a recess 14 which extendstherethrough. A stop lug 15 is provided on the bracket immediately belowand adjacent the aperture, and a pair of spaced locking members or lugs16 immediately above said aperture. A look hole 17 is provided in eachlock lug in aligned relation. The lock lugs and the lug 15 projectthrough to the exterior of the casing as shown in Fig. 2, while theopposite side of the bracket, also adjacent the aperture, isprovidedwith a pair of spaced bearing lugs 18 having aligned fulcrumholes 19. I

The nozzle support 20 comprises a rectangular shank 21 provided with abearing hole 22 and a connection hole 23 at its extremity, and abifurcated end having extending arms 23' slightly rounded upwardly andadapted to receive the shoulder 12 of the nozzle. This member ispivotally mounted between the bearing lugs 18 by the pin 23 whichextends through the hole 22 thereof and the fulcrum holes 19 of thebearing lugs; The nozzle support is thus mounted in the orifice of thebracket 13 with the shank portion extending into the casing, and thebifurcated arms extending a distance beyond the exterior of the casing.Pivotal movement of the nozzle support in a downward direction from theposition shown in Fig. 2 is prevented by the stop lug 15 whichimmediately underlies and abuts the same.

The shank 21 of the nozzle support is connected in any suitable mannerto the various control members of the pump. In the exemplary form shownin Fig. l a pair of connecting rods 24 and 25 is pivotally mounted by aclevis pin 26 through the connection hole 23. The rod 24 extendsdownwardly to the valve arm 25 of the control valve 2'7, while the rod25 connects to the switch arm 28 of the motor control switch 29. Whenthe nozzle support is in its inoperative or locked position, (Fig. 2,full lines), the control valve 2''! will be closed to prevent liquidpassage between the pump 2 and the meter 5, and simultaneously the motorcircuit controlled by the switch 29 will be opened by the movement ofthe switch arm 28, thus rendering the motor of the pump inoperative.When the support is in its operative position, (Fig. 2, dotted lines), areversal of the described action takes place, wherein the valve 27 andthe switch are restored to their operative or working positions.

The above description of the control connections discloses but one ofthe many possible control combinations. It is intended that the shank 21may be connected to the control members of any type of dispenser such asgravity feed, fluid pressure feed, or the hand operated type, withoutdeparting from the spirit of the invention. It

, will also be understood that types of nozzle supports and controls maybe utilized other than the telephone hook specifically illustrated, theobject being, however, as above set forth, to prevent operation of thefluid supply apparatus g through the control means therefor when thenozzle is placed on the support.

The nozzle 7 is adapted to be mounted on the nozzle support with thenozzle end 11 engaging upwardly through an orifice 30 in the casing 1and the shoulder 12 engaging between the arms 23 and the flat portion orthe trigger guard extending along the shank 21 to engage between thelock lugs 16. When the nozzle is thus mounted on the support, thecombined weight of the nozzle and attached hose will move the supportdownwardly from the position shown in dotted lines to the lower positionto abut the stop lug 15. When in the described lower position thetrigger guard is positioned between the lock lugs 16 immediately withoutthe line of the lock holes 17. The trigger, which is in its inoperativeposition is also positioned between the lock lugs and beyond the lockholes 17. The described position of the nozzle is attained by the simpleoperation of mounting the same on the arms 23 which properly space thetrigger and trigger guard for engagement with the lock lugs asdescribed.

When it is desired to lock the nozzle to the bracket 13 the bow 31 of apadlock 32 is engaged about the shank 21 of the support and through thelock holes 1 7 of the lock lugs thereby looking the controls ininoperative position, the trigger guard against upward movement, and thetrigger against movement relative the guard. Simultaneously the nozzleend is locked against removal and is protected against the elementswithin the casing 1.

When the padlock is removed the nozzle may be disengaged from thesupport and casing, subsequent to which the support may be manuallylifted to render the controls operative to supply the nozzle with liquidto be dispensed.
